INKSTAND.

SPECIFICATION forming part of Letters Patent No. 554,424, dated February 11, 1896.

Application tied my 21, 1891. serial No. 518,188. (No modelo To all whom it may concern:

Be it known that I, ROBERT G. Horxnvs, a citizen ofthe United States, residing at Somer ville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Inkstands, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention is an improvement upon that type of inkstand known as the automatic inkstand and in which a small receptacle at the upper end of a movable tube supplies the ink being used.

It consists in applying preferably to an inkstand of this character a device whereby the diaphragm of the stand is caused to be moved downward and held downward, whereby the ink is subjected to such pressure that it is caused to flow upward through the tube and fill the small receptacle andmaintain it filled for awhile, and when emptied the diaphragm is device is applied to an automatic inkstand it may be used in its usual way, which requires a downward movement of the small receptacle and tube for substantially each dip of the pen, or it may be used as above indicated.

In the drawings, Figure l is a view, in vertical central section, of an inkstand having the features of my invention7 representing the supplemental or additional ink-fount in its elevated position or that which requires a downward movement for each dip of the pen; and Fig. 2 represents the supplementalfount in its depressed condition, or that in which it is filled and maintained lled until the ink has been exhausted from it.

A represents the inkstand proper. It has a reservoir a, which is adapted to hold a` relatively large supply of ink. It is open at its top and has about its upper edge at the top the screw-thread a upon which screws a cap B, the cap holding upon the upper edge a2 of the main stand by its edge the flexible diaphragm O, preferably arched upward in place. This diaphragm supports the movable tube E which extends downward into the ink-well and upward through the cap, its upper end The cap B has a central hole b, in which screws an adjusting-nut F, and the cap may have the thread formedV by its edge alone7 orr it may have a downward-extending section b', in which the thread is formed. The nut F has a thread f to engage the edge of the cap about the hole or the threaded section thereof, and also an outwardly-extending iiange f' above the cap,which furnishes means by which it may be readily turned. It has a hole f2, through which the tube E extends and in which it is vertically movable. t

When the nut is in its highest position, the tube and fount E may be moved downward at each dip of the pen and the fount filled and emptied at each dip. By screwing the nut downward it comes into contact with the diaphragm O, depresses it and the tube E and the fount E', andthereby fills the tube and the fount and by holding the tube and fount depressed maintains them filled.

I would not be understood as limiting the invention to a stand having an arched diaphragm, as it may be employed in connection with a stand having any sort of a diaphragm the hole b, the nut F screwing in said hole and adapted to depress the diaphragm and tube when desired to fill and maintain :filled the ink-fount, as and for the purposes described.

2. The combination of the ink-vessel A, the diaphragm C, the nut F having the hole f2 and the tube E having the fount E, as and for the purposes described.
